Old-school magic meets the modern world when young Alex stumbles upon the mythical sword Excalibur. He soon unites his friends and enemies, and they become knights who join forces with the legendary wizard Merlin. Together, they must save mankind from the wicked enchantress Morgana and her army of supernatural warriors.

King Arthur, accompanied by his squire, recruits his Knights of the Round Table, including Sir Bedevere the Wise, Sir Lancelot the Brave, Sir Robin the Not-Quite-So-Brave-As-Sir-Lancelot and Sir Galahad the Pure. On the way, Arthur battles the Black Knight who, despite having had all his limbs chopped off, insists he can still fight. They reach Camelot, but Arthur decides not to enter, as "it is a silly place".

A surreal adaptation of Sir Thomas Malory's "Le Morte d'Arthur", chronicling Arthur Pendragon's conception, his rise to the throne, the search by his Knights of the Round Table for the Holy Grail, and ultimately his death.

When soldier Robin happens upon the dying Robert of Loxley, he promises to return the man's sword to his family in Nottingham. There, he assumes Robert's identity; romances his widow, Marion; and draws the ire of the town's sheriff and King John's henchman, Godfrey.

When the child Arthur’s father is murdered, Vortigern, Arthur’s uncle, seizes the crown. Robbed of his birthright and with no idea who he truly is, Arthur comes up the hard way in the back alleys of the city. But once he pulls the sword Excalibur from the stone, his life is turned upside down and he is forced to acknowledge his true legacy... whether he likes it or not.
